what are they exactly?...are they seat skins or seat covers?...if they're just cover then cover the existing seat with em...if they're skins then cut the old stuff off and hog ring the new ones in like the old ones were

You might do the duct tape thing, over the cracks, then just slide the covers over. Or you could just try it to see how it looks. I'll bet that once the covers and some sunshine make the cracks lay down flat, it will look good. I like mine, but didn't have serious cracking.

i picked up some upholstery tape at the parts store. it seems a little stronger and more flexible than duct tape. taped up the rips and and a few missing pieces and put the seat covers over it. they've been on for over three years and so far are holding up well.
